General Description

The OMEGA® FSW-50 Series Flow Switches feature a 15A SPDT switch

 

 

 

and an internal screw adjustment which provides continuous switch point

 

adjustment while in operation in-line. Multiple drag disks are supplied

 

with each unit to provide incremental switch point adjustment. Their non-

 

magnetic design makes them ideal for applications where rust is a problem.

 

The FSW-50 comes standard in a plastic/316SS construction. The FSW-50

 

Series is also available in a special PPS* Hastelloy C and Viton construction.

 

The FSW-50 Series are for use in highly particle-contaminated liquids

 

such as sewage, machine cutting oils and medium slurries. The standard

 

models can be used in mildly corrosive liquids such as low to medium

 

concentration acids and bases; sea water, sewage oils; rusty coolant water,

 

etc. The special PPS* Hastelloy C and Viton construction models are for

 

use in concentrated corrosive liquids such as sulfuric, nitric, hydrochloric

 

and acetic acids; ferric chloride; aqueous ammonia; benzene; magnesium

 

chloride, etc.

 

Particle contamination resistance is provided by a flexible filter boot

 

which prevents crystallization, caking, heavy dirt concentration, slurries,

 

scum, etc., from affecting the operation of the flow detector. The FSW-50

 

Series Switches respond to flow only, independent of line pressure,

 

temperature and environment.

 

During emergency conditions these switches signal catastrophic system

 

failures such as line breakage; pump failure; incorrect valve opening or

 

closing; pipe, valve or filter clogging, etc.

Specifications

FLOW RANGE (water calibrated @ 70˚F)

The maximum flow range flexibility is provided by three adjustment options:

1. Continuous adjustment while operating via a calibrated FORCE/BALANCE spring.

2. Step incremental adjustment via drag disk size change.

3. Continuous adjustment via moment arm change.
